title: Pd(II)-catalyzed Ph2(O)P-directed C-H olefination toward phosphine-alkene ligands.
abstract: The Pd(II)-catalyzed Ph2(O)P-directed C-H olefination to synthesize alkene-phosphine compounds is reported. In contrast to previous examples of various directing groups that guide selective C-H activation, the Ph2(O)P group not only acts as the directing group but also serves to construct the alkene-phosphine ligands. The monoprotected amino acid (MPAA) ligand Ac-Leu-OH is found to promote this reaction in a significant manner.
